The Mac Mini seems to have disappeared from a lot of UK shops that did sell them. It's no longer on the PC World website or John Lewis. I emailed John Lewis, a major supplier of Apple in the UK regarding the availability of the Mini. Here is the response I received. The 82702306 product code refers to the 2ghz SuperDrive version. Now, they also say that they have others in stock which should be available on the website, so whether that refers to the 1.8ghz ComboDrive version, i'm not sure.
